In initial 12 weeks of pregnancy ,foetus needs thyroxine for formation but cannot secrete by its own. Hence foetus derives thyroxine from mother blood, hence your dose was increased. Get your thyroid profile checked every month.

Hello, Thanks for the query, I have seen the details given. During the gestation period TSH should be maintained in the following manner : 1st Trimester : 0.1 to 2.5 mU/L, 2nd Trimester :0.2 to 3 mU/L & 3rd Trimester 0.3 to 3.0 mU/L Considering the above values your current TSH value is well with in normal limit. Hence, continue the current dosage of Levothyroxine. Plus check TSH once every 4 weeks till the end of gestation period. This essential for normal fetal development and desired outcome of pregnancy. If you have any questions please do come back. Thanks.
